PORTABLE ELECTRIC LAMY* Application filed February 26, 191.6.

To all whom it may concern Be it known that I, ERwIN W. LAMB, a citizenofthe United States, residing at Lansing, in the county of Ingham andState of Michigan, have invented certain new and useful Improvements inPortable Electric Lamps; and I do hereby declare the following to be afull, clear, and exact description lof the invention, such as willenable others skilled in the art to which it appertains to make and usethe same.

This invention relates to new and useful improvements in portableelectric lamps and the principal object of the invention is to provide alamp which maybe readily transported and is particularly attractive inappearance.

Another object of the invention is to provide a lamp which may bereadily constructed of any suitable wood or other desirable material andwhich is particularly simple in construction and may be easily puttogether.

A further objectolf the invention is to provide a novel means forsupportingthe controlling switch in the base of the lamp which may bereadily attached or removed therefrom at the desire of the user.

lVith these and other objectsin view, the invention consists in thenovel combination and arrangement of parts which will be fully set forthin the following specification and accompanying drawings, in whichFigure 1 is a side view partly in section of a lamp constructed inaccordance with this invention. Fig. 2 is an edge viewof Fig. 1.

Fig. 3 is a bottom plan View of the lamp base. Fig. 4 1s an enlargedsectional view through a fragment of the base showing the method ofsupporting the switch in place, and Fig.- 5 is a detail perspective viewof the switch supporting hood.

Referring to the drawing the numeral: 1 designates as an entirety thelamp stand consisting ofthe base block 2. This base block is provided'in its under side with a plurality of openings 3 which are arranged nearone edge and are adapted to receive plugs of lead or other suitableweighting material 4. A rectangular recess 5 is formed in the block andopens outwardly through the bottom face thereof and this recess extendsupwardly a distance equal to substantially one-half of the thickness ofthe base bloc'lr'and thenis reduced as at 6, to form a shoulder 7, theuse of which will appear as Y the' description proceeds.

tion of said aperture extends to a point near the upper face of theblock and a central circular opening 8 extends through the wall betweenthe upper face of the block and the upper terminal of the reducedportion l as clearly shown in Fig. 4. Formed in the block and extendingfrom the rear wall of the opening 5 rearwardly to a point in alinementwith the opening in the standard which will be more fully hereinafterdescribed is a bore 9 which forms conduit-through which the wires whichwill be more fully hereinafter described extend. Secured to the upperface of the block and spaceda distance from the rear edge equal to thedistance from which it is spaced from the side edges is a suitableplinth 10 provided in its upper surface with a recess 11 for thereception of the extension onthe standard which will be more fullyhereinafter describedl This plinth is attached to the base -2 bysuitable screws or any other attaching means 'and is provided lwith acentral opening 12 which alines with the opening 13 which communicatesat its lower end with the bore 9, and is formed in the base block 2. Thestandard is designated by the numeral 14 and comprises a rectangularstrip of wood or any other suitable material having extending upwardlytherein an axial aperture or bore 15 which alines with theopening 12 inthe plinth 10 and cooperates therewith in forming a conduit for theconductor wires.

The bore 15 extends upwardly through the standard 11 to a pointsubstantially onethird of the length of the standard from the upper endthereof as clearly shown in Fig. 1.

Formed in the upper end of the standard and extending transverselytherethrough is an opening 16 for the reception of the rear end of thesupporting arm 17.v This supporting arm is preferably rectangular incross section as shown in Fig. 2 and is secured in the opening 16 ina-'ny suitable manner. Av brace rod 18 extends from a point l below theopening 16 in the standard 14eto a point intermediate the ends of theslipporting arm and this brace rod is formed with an opening 19 whichcommunicates at its lower end with the opening 20 which is formed at theupper terminal of the bore 15 and extends upwardly and forwardlytherefrom in the standard 14;. vThe upper termiwardly and forwardly andat its. forward hood illustrated in Fig.

lNhile in the foregoing there has been shown and describedthe'prefer'red embodiment of this invention, it is to be understood thatsuch changes maybe made in the combination and arrangement of parts aswill Yl'all within the spirit and scope of the appended claini.

What is claimed is v ln a lamp of the class described, a base haring arecess near its forward edge extendin r upwardly from its lower face, areduced recess extending upwardly from the irst mentioned recess to-apoint near the upper side of the base, shoulders formed at the-junctureof the recesses, the base also having an opening'extending through thetop and communicating Witl1 'the reduced recess, said opening beingarranged centrally of the recess, a hood comprising a body, side wallsformed on the body,t11e body also uwing a. central aperture thereinalining with theaperture in the upper end of the reduced recess, flangeson the lower ends of the walls for engaging the shoulders, screwsadapted to pass through the flanges to hold said hood in place, aswitch, a reduced neck on the switch adapted to extend through theapirture ii the hood and lock nuts for engaging o posite sides of thehood innue- 'diately adjacent the aperture to hold the switch in place.

ln testimony whereof I aiix my signature in' presence of two witnesses.
